MB Series S Type AC Centrifugal Fans / Blowers

Centrifugal Fans / Blowers

Centrifugal blowers move air by means of the centrifugal force generated by rotating a cylindrical runner on which blades have been arranged. Centrifugal blowers have a small outlet, which concentrates air in a single direction and are therefore suitable for local cooling. They also create large static pressure, making them optimal for cooling equipment through which air cannot flow easily and for airflow through ducts.

Air is Drawn Up Through the Ducts

(Supports Intake Air Temperatures of -10°C to +90°C)

The MB Series' special design for use with ducts improves the ability to install with ducts.

easy duct installation

Ducts can be installed directly using the step

Duct joints (sold separately) connect duct and exhaust

Blows Liquids and Powders Off without Direct Contact

Centrifugal Fan / Blower Blows Liquid and Powder without Direct Contact

The air flow directionality of the MB Series can be used to blow liquids and powders. No need for humans or robots to touch the work piece.

Manual airflow adjustment with control damper

Work Piece Alignment is Maintained During Transport

MB Series S-Type suction maintains work piece alignment

The suction power of the MB Series is useful in preventing lightweight or thin work pieces from scattering or becoming misaligned.

Risk of process errors or loss. Reordering improves in-proocess defects

Installation Methods

The blower can be installed according to your needs using the mounting holes and mounting brackets. Accessories are also available to make installation convenient.

MB Series S-Type installation methods

Air Flow Adjustment

Air flow can be adjusted manually by using an air flow adjustment damper (sold separately).

Thermostat

Thermostats automatically perform ON/OFF fan control in accordance with the temperature fluctuation inside the equipment. It helps improve the equipment's "environmental" performance relative to energy savings, noise reduction, etc.

Air Flow Adjustment Damper

The airflow adjustment damper is peripheral equipment that can be attached to the intake to allow for easy manual adjustment of the air flow. A numerical scale is engraved on the damper. This can be used as a marker when adjusting the air flow.

Filters

When using a fan to cool machinery, dust may accumulate inside the machinery after long periods of operation. Depending on the parts involved, this could cause a malfunction. These filters prevent dust from entering the device, keeping the air inside the machinery dust free.
